Assistance with finding/building Driver

Thanks Tech!

Any time. Good to hear you're doing it the right way.

Use this charger.

DealExtreme: $12.58 Ultra Fire 10440 14500 Ac Charger

It charges both 10440 (AAA) and 14500 (AA) batteries in case you want to make another build with bigger batteries.

I probably should get one of those too...lol...I think the one I have is only Nimh/Nicd, xD

Who the heck are YOU?

Way to spam the thread.

Not all Li-Ion batteries will drop from 4.2V to 3.8V in under a minute. If you are using 2 18650's, you will have significantly longer regulated runtime than if you were using 2 10440's. With a boost driver, you get regulation for the whole time, but since you are boosting the voltage, you are pulling more current from the cell at 3.6V than you are sending to the LD at 5V. At some point, overdischarging the Li-Ion cell may become an issue.

"Check out my BR lazor, it burnz at 900mW!"
*Cue single 10440 cell venting with flame*

So, under certain circumstances, I could see using only 2 Li-Ions as feasible. But having control over the entire build, you shouldn't have to make that sort of concession.

No offense, but I'd bet my right testicle that Dave has a LOT more knowledge than you when it comes to this sort of thing, not to mention that I know from personal experience that he's right.

I received the driver today, but it appears to be faulty, x.x
I was grounded when I took it out of the package with a grounding wrist strap that I use whenever I'm modifying my computer, so no worries there. Anyway, when I hooked up my battery to the + and - sides, I measured the mA with my multimeter, and it didn't give me any reading at all. It was a new 12v A23 The batteries in the meter are good as I just replaced them around two weeks ago, so my meter can't be off. It just gave me a 0.00 on the multimeter screen. I tried the 2mA, 20mA, and the 200mA settings, and it all came out as 0.00's on all three, I'm going to send an e-mail to rkcstr about it. Seems odd to me though, ah well.

Did you read the manual clearly?

Yep, He's been giving me trouble shooting help, looks like there's a short, but there's no visual short that I can find, so I don't know, o.o
